Multi-Frame Image Processing of Himawari-8/AHI Data

抄録

The Japan Meteorological Agency successfully launched Himawari-8 in October 2014, and began operations in July 2015. A new sensor system, Advanced Himawari Imager (AHI), is observing the surface of the Japan area frequently (every 2.5 min) and 24 images can be observed sequentially each hour. This study examined the feasibility of multi-frame image processing using Himawari-8/AHI data obtained over one hour. Slight distortion of images was adjusted by dividing one pixel into ten subpixels and by applying automatic registration, which facilitated multi-frame image processing. As a result, Himawari-8/AHI data is improved effectively to allow closer observation of the details of an image.
